====== Selection Sequence ======

In a selection sequence, several selection questions are shown one after the other (sub-questions). The sub-questions are displayed on the screen one by one. The options are displayed in boxes and are selected by clicking on them -- the next sub-question appears immediately after this. The selection made by the participant cannot be changed afterwards.

Technically speaking, a selection sequence question is a little unusual: it does not consist of individual questions, but rather a collection of several selection questions (sub-questions). Each sub-question has a question title and possible options. Therefore, sub-questions are added to the question, instead of item -- to the left in the **List of Questions**. 

This question is ideal for measuring response times, for surveys on a [[:en:create:smartphones|smartphone]], or if the questionnaire should look little bit snazzier. The options can be arranged one below the other, side by side, or in a square. 

**Note:** Do __not__ input a question title for the question itself, unless this should appear above all of the sub-questions.

**Note:** Response time can only be measured from the second sub-question onwards. If you want to measure response times, write an explanation (or something similar) for the first sub-question, and "Next" as the option. 

**Note:** Place the question by itself on a questionnaire page -- or at least as the last question on the page. After the last sub-question has been answered, it will continue automatically to the next page in the questionnaire.



===== Advantages =====

  * It is more convenient to select options from large boxes than small selection fields.
  * As the participant cannot press the "Next" button between sub-questions and does not have to wait for a new questionnaire page to be submitted, filling out the question is quicker and easier.
  * The question enables reaction time to be measured reliably from the second sub-question onwards.  The reaction time is measured in milliseconds with an accuracy of around 10 ms. 
  


===== Disadvantages =====

  * Whereas in a normal selection the first-selected option can still be amended,  it is not possible to change the selection made in a selection sequence. 
  * The question should be put on a questionnaire page by itself.
  * The progress bar does not change while the question is being filled out.
  * A maximum of 20 options are possible per sub-question.
  * Filters between sub-questions are not possible. 
  * The selection sequence needs [[:en:glossary#javascript|JavaScript]] to function properly. If JavaScript is disabled, a different layout will be shown and response time measurement will be deactivated.
